The Canon de 138 mm Modèle 1893 was a medium-calibre naval gun of the French Navy used during World War I and World War II. It was carried by a number of ships built during the 1890s including the Charlemagne-class pre-dreadnought battleships. Guns from scrapped warships were later mounted on auxiliary ships during the 1930s.
